Over several years, a fuel economy test measurement technique has been developed to highlight the magnitude of benefits expected in real world applications of different heavy-duty vehicle (HDV) engine oils in an operating vehicle. This method provides discriminatory results using an alternative to the widely used gravimetric fuel measurement methodology of Brake Specific Fuel Consumption (BSFC), in order to measure gains of <2% in a more repeatable manner. For the results to prove meaningful to the wider commercial audience, such as vehicle operators, original equipment manufacturers and oil providers, the systemic test vehicle operating conditions need to closely represent on-road conditions experienced on a daily basis by long haul, heavy duty diesel vehicles. This paper describes the parameters, necessary measures and methodologies required to record real world data and create representative proving ground test cycles.

Increased awareness of preserving the environment has motivated the development of a wide variety of environmentally compatible products. Such products include environmentally compatible lubricants. Sale and use of these types of lubricants illustrates diligence by the lubricant manufacturer, original equipment manufacturer (OEM), and the consumer in contributing to a cleaner environment. The use of this type of lubricant could enhance the image of the lubricant manufacturer and vendor as well as the equipment manufacturer who employs such a fluid. To base such a lubricant on a vegetable oil creates a product environmentally friendly by its farming origin and its ability to readily biodegrade if released. No machinery is so uniquely suited to using vegetable oil based lubricants as agricultural equipment. Since this equipment is particularly close to the environment, the lubricant can easily come in contact with the soil, ground water, and crops.
